in order for the inverse of f(x)=sin 2x to be a function, the domain of f can be limited to

Solution

If we graph f(x) = sin 2x we will see that the fuction is decreasing in the interval[pi/4,3pi/4].

So if we restrict the domain in this interval we will get the inverse.

Hence the correct option is c.
